RIDING-HARROW.

SPECIFICATION forming part of Letters Patent No. 704,500, dated July 15, 1902.

Application filed September 26,1901. Serial No. 76,621. (No model.)

T0 a/ZZ whom it may concern:

Be it known that I, LEWIS P. BLOOD, a citizen of the United States, residing at Runnells, in the county of Polk and State of Iowa, have invented a new and useful Riding-Harrow, of which the following is a specification.

My object is to facilitate the adjustment and operation of harrows by a person seated on the carriage to which the barrow-sections are adj ustably connected as required to make the harrows operative and inoperative at pleasure while the carriage is advanced across a eld or from one place to another.

My invention consists in forming and combining barrow-sections to adapt them to admit carriage-wheels to travel between the sections, to form tooth-bearing bars and pivot teeth to them so the teeth can be set at any angle desired for practical use and made inoperative by folding them into grooves in the bars in runners connected with harrow-sections for supporting and advancing the sections when elevated into vertical planes at the sides of the carriage-wheels, in a carriage adapted for combining and operating barrow-sections between the carriage-wheels and also outside of the carriage-wheels, in combining mechanism with the carriage and the barrow-sections for adjusting and suspending the barrow-sections by means of levers at the sides of the drivers seat, and in combining the barrow-sections and the carriage with a drag-bar, all as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 is a top view showing the forms and relative positions of the different parts. Fig. 2 is a rear elevation and shows one of the barrow-sections suspended in an inoperative position and the mating section hinged thereto in a perpendicular plane and supported uponlrunners fixed thereto as required in advancing from one field to another and also as required for passing through gateways narrower than the width of the harrow when all the sections extend in horizontal planes. Fig.

enlarged transverse sectional view of the teeth-bearing bars made of channel iron. Fig. 6 is an enlarged detail view showing how the slidable teeth-bearing bars and the teeth are retained in locked position in the harrowsections.

The numeral 10 designates the carriage-axle, and 1l and 12 the traction-wheels on the ends of the axle. The axle is preferably made of channel-iron and portions utilized for placing a wrench and other tools therein. Covers 13 are fitted on the portions that serve as toolboxes. V-shaped frames 14 and l5, made of flat bar-iron, as shown in Fig. 1, are fixed to the end portions of the axle 10 in any suitable way to extend forward and terminate in eyes 16, that adapt them to be pivotally connected with a drag-bar 17 by means of clevises 1S and eyebolts 19. A doubletree 20 is connected with the drag-bar 17 as shown in Fig. l or in any suitable way.

A drivers seat 2l is fixed to the cent-er of the axle 10, and a foot-rest 22 is fixed to the frames 14 and l5.

Metal frames 23 and 24 are fixed to the end portions of the axle 10 to project vertically and to serve as means for connecting harrowsections therewith and also hand-levers and devices for adjusting and controlling the harrow-sections while in operation and elevating and carryingthem inoperative. A fender 25 is fixed to the top portions of the frames 23 and 24 to arch upward in front of seat 21 and to serve as a means of protecting a person on the seat from falling forward from the seat.

Four barrow-sections are hinged together and at each side of the carriage and adjustably connected with the fixed frames 23 and 24. The straight tooth-bearing bars 26 of theA barrow-sections are made of channel-iron that hasflanges at its parallel sides, and flat cross-bars 27, 28, and 29 are fixedto the bars 26 in such a manner that the bars 26 will be parallel to each other in each section and each harrow-section inclined relative to the line of advance when in operation, as shown in Fig. 1. The center cross-bars 28 extend and terminate in hinge members connected by means of U-shaped bolts 30. The end crossbars 27 also extend and are hinged together in the same way by means ofY U-shaped bolts 30. The contiguous ends of theharrow-sec- IOO tions thus formed are hinged together by means of hinge members 3l, fixed to the crossbars 29 and hinge members 32 by means of U-shaped bolts 30, as shown in Fig. 1, or in any suitable way, so as to allow the harrowsections independent vertical motions. Mating flexible harrows each composed of four sections are thus constructed and combined and adapted to be adjustably connected with the carriage in such a manner that they will surround the carriage-wheels and to be adjusted relative to each other and the carriagewheels by a person on the drivers seat.

The diamond-shaped space thus produced between the four barrow-sections allows a tractionwheel of the carriage to tread the ground within that space, as shown in Fig. l, and also allowsv the two barrow-sections on the outside of the wheel to be placed in a vertical plane to be supported and advanced upon the runner 42. f

Rock-shafts 33, made of round irons ben double at their centers to produce integral arms 34 and curved at their end portions, are mounted in bearings at the tops of the frames 23 and 24. The curved ends of the rockshafts terminate in journals 35, to which are pivoted hangers 36, and the lower ends of the hangers are fixed to the U-shaped bolts 30, that connect the ends of the center cross-bars 28 of the barrow-sections. The four harrowsections at each side of the carriage are thus connected with the carriage by means of the rock-shafts 33, and hand-levers 37 are fulcrumed to the tops of the fixed frames 23 and 24 and pivotally connected with the tops of the arms 34 of the rock-shafts by means of links 3S in such a mannerthat the rock-shafts can be operated by means of the levers asv required for raising and lowering jointly the four harrow sections suspended from 'the ends of the rock-shafts.

Curved bars 39 are pivoted to the journals 35 at the ends of the rock-shafts 33 and pivotally connected with the centers of the central bar 26 of the barrow-sections on the insides of the carriage-wheels.

Curved bars 40 are pivotally connected with the central bars 26 of the harrow-sections outside of the carriage-wheels and detachably connected with the central cross-bars 28 of the harrowsections inside of the carriagewheels by means of spring-bolts 4l or in any suitable way, so the harrow-sections can be turned inward relative to the carriage and project in vertical planes to travel on runners 42, fixed to the free ends of the inner tooth-bearing bars 26, and when the outside sections are in horizontal positions the inner ends of said bars are pivoted to the journals 35, as shown in Fig. l.

In the lower ends ofthe fixed frames 23 and 24 is a rack 43, and 44 is a pawl pivotally connected with the lower end 0f each lever 37in such a manner that the pawls will engage the rack as required to lock the levers in fixed positions. Rods 45 are connected with the pawls at their lower ends and at their top ends with handles 46, pivot-ed to the upper ends of the levers for operating the pawls to lock and unlock the levers as required for thereby raising and lowering the barrow-sections.

Chains 47, xed to the center of the axle 10 and provided with hooks at their free ends, adapt them to be detachably connected with the cross-bars of the barrow-sections to aid in retaining the harrow-sections elevated and inoperative.

The flanges of the tooth-bearing bars 26 are turned inward to produce bearings for channel-bars 49, that have flanges that overlie the said bearings of the bars 26 and are thus slidably connected to the bars 26. Each bar 26 has a bar 49 thus connected therewith, and the bars 49 in each harrow-section are rigidly connected by cross-bars 50, fixed thereto atk their central portions, so they can be moved backward and forward jointly as required to adjust the teeth 5l, pivoted in the channel-bars 26. By providing slots in the channel-bars 49 the curved teet-h can be extended Ydown through the bars and between rivets fixed in the bars, as shown in Figs. 4 and 5, and by moving the bars 49 relative to the bars 26 the teeth can be set at any angle desired and also folded into the channel-bars 49 to cover and protect the teeth as required to facilitate handling the harrow sections when not in use.

Spring-bars 52, fixed to the cross-bars 50 and provided with teeth adapted to engage the end cross-bars 27, serve as. a means for locking the adjustable channel-bars 49 and the teeth 5l in fixed positions relative to the frames of the barrow-sections composed of the bars 26 and cross-bars fixed thereto.

Each one of the four front barrow-sections has a fixed hinge member 53 and a link 54 hinged to said member in such a manner that by means of the clevises 18 at the center of the drag-bar 17 and clevises 55 ou the ends of extensions 56, hinged to the ends of the drag-bar, the harrow-sections are adjustably connected with the drag-bar in such a manner that the barrow-sections on the outsides of the carriage-wheels and the hinged extensions on the end ofthe drag-bar can be turned upward to be jointly retained in vertical planes, as shown in Fig. 2.
